Preparation

Line 2 baking sheets with parchment paper and set aside.

In the large bowl of your stand mixer (or using a hand mixer) cream butter and both sugars together. Stir in the eggs and vanilla, whipping until fluffy and lighter in color. Dump in all of the dry ingredients (everything else except the chocolate chips and berries) and stir until just incorporated. Fold in chocolate chips and blueberries. Chill dough for about 20 minutes. Preheat oven to 350 F.

Using a small scoop, scoop cookies onto the baking sheets spacing them about 2 inches apart and press down lightly to flatten. Bake 10 minutes or until the edges are golden brown. Remove pans from the oven and set them on a rack. Cool cookies for 3 minutes on the baking sheet and then transfer to a cooling rack to cool completely.
